The passenger service unit further includes a touchless sensor configured to detect a presence of an object in a vicinity of the touchless sensor, and to output a signal for controlling the output device in response to detecting the presence of the object.

Abstract: An aircraft lighting health monitoring system is disclosed. Aircraft lights include each include one or more sensors. Multiple lights having such a sensor(s) are operatively interconnected with this common aircraft lighting health monitoring system. A CPU of this aircraft lighting health monitoring system may be maintained in a sleep mode until needed to assess sensor data of a first data classification, at which time the CPU is used for this assessment and outputs an appropriate health status communication to one or more displays. A DMA controller of the aircraft lighting health monitoring system may be used to handle sensor data of a second data classification (e.g., to control storage of such sensor data).
